They don't make as much power as it cost to run the car. The car has losses, ie. energy absorbed in to the tyres, road, transmission, suspension components, light, heat, basically everything that is going on. The alternator gets what's left over and even then introduces it's own frictional losses just by turning. You would never power an electric car from an alternator as there will always be mechanical losses, however small you manage to make them.

Im sure somone will come along in a minute and try and argue that perpeptual motion is possible.

.... Emission free out of the car yes... But where does the electricity come from??? OH YES  Emissions at the power plants.
Plus the fact that naturally if everyone drove an electric car, the national grid of eletricity providers could not cope.
They generate the electricity from water/hydrogen, afaik merc aren't expecting you to go home and plug your S class into an extension hanging out the kitchen window.
It would also take about a day to charge up, totally impractical.

Yes electricity can be generated from natural ways Solar, Wind, Hydro... HOWEVER this is only a small % provider for our current electricity needs. IF Everyone was to be using electric powered cars then can you imagine 8 million cars or more in the UK alone being constantly plugged into the national grid? We definately couldn't cope with providing that much electricity now and those 'Eco friendly' ways wouldn't come close to providing enough electricity alone.
Thus... to provide the energy required to power loads of electric cars you're looking at having loads of big power stations polluting to produce the power.

... which is actually worse as you concentrate the pollution to where the power stations are.

cars have alternators which generate electricity, can't imagine it being hard to create one good enough to generate a larger amount of power to charge the batteries. Which in essence would be no pollution.
What you are essentially talking about is across between what there already is (Hybrid cars, which recharge when moving / the engine is driving) and perpetual motion (where the energy used to move is regathered and used to charge the batteries)
The first (Hybrid) still requires an engine burning fuel, therefore these '1015 completely fuel free, 100% electric cars' would not be able to use this.
And secondly, as Ian described, you can't simply have a alternator generate the power from the car and thus make the car charge itself up... the amount of power being used to drive the car forward would far exceed the amount able to charge it back up again (losses and unefficency as mentioned by Ian).
The final thing is the fact that these electric car's batteries will no doubt wear out and not recharge as well as they used to after a while and we'll be left with huge rubbish tips containing old batteries and worn out electric motors with fucked brushes.

Paul_J, what I mean is that you'll pour water into the car and the hydrogen and electricity will be created there, nothing to do with power stations.

I actually chuckle at the westerners that complain about China's Pollution. The only reason they're polluting so bad is that the majority of our industrial work is done over there. Therefore we have less pollution from industry. However I do agree the chinese make no attempts to do things in a eco friendly / more efficent way - but still, the only reason they're needing all that power is to provide us westerners with our lifestyle products.

That would be awesome, shit out if you are on a meter though

But a hydrogen fuel cell is one efficient piece of kit so the ammount of water you'd need is very little.
But then we might have problems with oxygen pollution

Apparently, its costs half the price of race fuel but uses twice as much!

You imagine Oxygen displacing Co2 and Plants / Tree's dying or the climate getting so cool people start saying a new ice age is approaching...
Have that Eco Cunts
I'll be driving around in my petrollium Ferrari 355 and porsche gt3 rs to balance it all out
